Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction
Sebastián Castilla, Bernat Terrés, Marta Autore +11
Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of se…
Impact of thermal annealing on graphene devices encapsulated in hexagonal boron nitride
S. Engels, B. Terrés, F. Klein +6
We present a thermal annealing study on single-layer and bilayer (BLG) graphene encapsulated in hexagonal boron nitride. The samples are characterized by electron transport and Ram…
Spatial control of laser-induced doping profiles in graphene on hexagonal boron nitride
Christoph Neumann, Leo Rizzi, Sven Reichardt +6
We present a method to create and erase spatially resolved doping profiles in graphene-hexagonal boron nitride (hBN) heterostructures. The technique is based on photo-induced dopin…
Low B Field Magneto-Phonon Resonances in Single-Layer and Bilayer Graphene
Christoph Neumann, Sven Reichardt, Marc Drögeler +6
Many-body effects resulting from strong electron-electron and electron-phonon interactions play a significant role in graphene physics. We report on their manifestation in low B fi…
Raman spectroscopy on mechanically exfoliated pristine graphene ribbons
B. Terrés, S. Reichardt, C. Neumann +3
We present Raman spectroscopy measurements of non-etched graphene nanoribbons, with widths ranging from 15 to 160 nm, where the D-line intensity is strongly dependent on the polari…
Nanosecond spin lifetimes in single- and few-layer graphene-hBN heterostructures at room temperature
Marc Drögeler, Frank Volmer, Maik Wolter +6
We present a new fabrication method of graphene spin-valve devices which yields enhanced spin and charge transport properties by improving both the electrode-to-graphene and graphe…
Negative quantum capacitance in graphene nanoribbons with lateral gates
R. Reiter, U. Derra, S. Birner +4
We present numerical simulations of the capacitive coupling between graphene nanoribbons of various widths and gate electrodes in different configurations. We compare the influence…
Transport in coupled graphene-nanotube quantum devices
S. Engels, P. Weber, B. Terrés +6
We report on the fabrication and characterization of all-carbon hybrid quantum devices based on graphene and single-walled carbon nanotubes. We discuss both, carbon nanotube quantu…
